When you come, the stars and the moon are traveling together, and when you return, the same is true for you.

Time is tight.

After returning to Yingtian, there were more than twenty days left before the wedding date, and the dusk was a little unbelievable. Under this traffic situation in the fifteenth century, I actually ran more than 8,000 kilometers back and forth in more than a month.

It's simply incredible.

This trip costs a lot.

The car and horse fee alone is a huge sum of money. There are seven or eight horses running to death along the way. The remaining horses are basically useless and can no longer run long distances.

The labor costs of the four coachmen and the expenses along the way are added together, and they are also thousands of taels of silver.

And the result is only ten magnets.

Investment and output seem to be inconsistent, but this was the fifteenth century. With this magnet, the subsequent benefits it brings to oneself are definitely not measured by thousands of taels of silver.

After returning home, he asked Qian Feng to go to Xu Mansion to report his safety.

It didn't go to dusk.

He still has something to do, and he has a day off.

Early the next morning, I went to Zhongshan's factory to find Lao Li to test his work results.

Perfectly done.

Except for the remaining ten kilograms of copper that were told at dusk, the remaining 280 kilograms of copper were poured into copper wires and welded together, with about 450 meters of copper wires.

Enough!

It is not enough to have copper wire, and insulating substances are needed. If there is no insulating substance wrapped, the effect and quality will be very poor, and there will be safety hazards.

There are two options that can be used for insulators.

Ceramics and paint.

Lacquer has been available since ancient times and in the Ming Dynasty, but it is expensive, but it can still be purchased.

Ceramics can be customized.

Dusk plans to do a two-pronged approach.

He asked Xu Yin to go to the market to buy paint, and in the evening, he went to the ceramic kiln that customized the exquisite small porcelain bottles. He found his boss and made a request, hoping that the other party could complete his order.

When the other party heard the request of the dusk, he felt a headache. This type of porcelain had never been made before and needed to try it a few more times. He said, "The length of the porcelain pipe you requested is too long and it is not easy to pull the embryo. If we want to do it, we can only do our best to pull out the length within the range of our ability. If we grow it, it will be impossible, so we need to try it many times."

After thinking about it, I said I didn’t need to try it. Just do it as I said, make a large number of finished products and burn it in one kiln. Even if there is one of the ten, it is OK.

When the owner of the kiln burner heard this, he silently calculated in his heart, "According to one out of ten, he may have to make hundreds of samples to meet the requirements you need, and this cost is very high."

Xun smiled and said, "You won't suffer any loss."

The boss hesitated, "Okay, you can try it, but the ugly thing is ahead. If the last one is successful, you still have to pay for the money. I can't let my workers do it in vain."

Dusk nodded, "This is nature."

He also said: "But I have another requirement, hoping that these porcelain pipes must be glazed inside and outside."

The boss wondered, "The outer glaze is for the sake of good looks, but why is the inner glaze?"

It is not easy to explain at dusk, so it is vague.

The inside is glazed to avoid damaging the copper wire. There is no way, the copper wire is difficult to obtain, and if the copper wire is damaged, it will lead to safety accidents such as burning the wire. It is better to spend more money and do it at one time.

After paying the deposit, I immediately returned to the city to prepare for other things at dusk.

Making wooden boards.

Making rollers.

Making various types of washer - they are also polished with wood chips and polished into a washer style. Fortunately, the woodworker is very skilled and it is not difficult to make.

Then use wooden boards to create a U-shaped frame.

Everything is ready.

At dusk, I bought bamboo of various colors and found a carpenter. I cut the bamboo into a tortuous shape of earthworms, just like a winding mountain road. After making a certain amount, I would steam it all.

Finally, I sent someone to Zhongshan Factory to get it back, the spherical glass container that Lao Li blew out during this period, namely the light bulb.

Don’t say, Lao Li has a few brushes.

It actually did it.

But not many, only seven or eight. In Lao Li's words, don't underestimate these seven or eight. This was how many days he had failed countless times before he could get these few.

Let the carpenter accurately measure the size and use bamboo pieces to make the block of the light bulb to ensure the sealing inside. Of course, paint must be painted to ensure that it is truly airtight.

Put the wick made of bamboo as material into the bulb, connect the copper wire, and leave half of the two poles to facilitate testing wiring, and then start building experimental equipment.

When the U-shaped frame is in place, first open a hole in the center of the roller, then wrap it with copper wire, pass the wood-made rotor through the U-shaped frame, then through a hole in the roller, put it in a magnet, pass it through another section of the roller, and mount it on the U-shaped frame.

Connect the left and right ends of the copper wire on the roller to the light bulb.

Since then, a small generator has been formed.

Whether it can be successful or not, I feel unsure of the dusk.

Only continuous experimentation.

Fortunately, there were enough materials to give him several chances of failure.

...

...

Time passes.

The end of the year is approaching, and the second half of the second year of Yongle seems to be about to pass without wind and rain.

The wedding date is approaching at dusk.

Under the operation of Wu Pu and Wu Li, all preparations for the wedding were carried out in an orderly manner, and the invitations were dispersed, radiating the entire Nanzhen Fushi.

In addition, Wang Zhen, who lives near the Imperial College, was also invited by Gao Xianning.

Zheng He, the official supervisor of Da Nei, and the eunuch Gou'er received the invitation.

Daoyan, the old monk from Jianchu Temple, was also invited.

Even Zhu Di and his wife received the invitation.

There are many relatives on the Xu family, but they are invited one by one, but most of the relatives there stay in the Xu family, and only a small number of relatives will come to see them off, and then they will have lunch here at dusk.

It seems that this is just an ordinary happy event of romance and romance.

However, with a negotiation between Empress Xu and Zhu Di, no matter what happened, news leaked from the Xu Mansion that on the wedding day, Empress Xu would personally leave the palace to see her off to see her off.

This news made the sensitive Yingtianren suddenly feel unusual.

Empress Xu is going to leave the palace, so what about Zhu Di?

Previously, Zhang Dingbian descendants proved that Xun was a member of the Ming Cult, and in the end, there was a heavy thunder and little rain. Zhu Di did not punish Xun either. Later, he even asked the military weapon supervisor to send 300 kilograms of copper to Xun.

Copper is not an ordinary thing.

From this we can see that Zhu Di trusts in the dusk with great confidence.

So even Empress Xu is coming to attend the evening wedding. Will Zhu Di also be able to leave the palace?

Very likely!

So Yingtiancheng suddenly became nervous.

Zhu Di did not leave the Forbidden City, and there were the Emperors' personal guards such as the Jingying and Jinyiwei. No one could do anything to him, so the Shangyuan Fire Case was in trouble. But now, Zhu Di was about to leave the palace, how could the old Jianwen officials hidden in the darkness not be ready to move?

Everyone in the court and the country knew that with Zhu Di leaving the palace, I was afraid that Yingtian City would become lively.

But then I thought about it.

Would Zhu Di not know?

Therefore, this time I leave the palace, there will inevitably be a tight security guard, and there will be absolutely no accidents.
